My grandfather worked on the bomb that was dropped on Hiroshima, and it troubles me.

Hello, my name is Shirin Neshatz. I'm an Iranian-born visual artist and filmmaker living in New York.

has to be carefully coded so I can escape being a target for the Iranian government.

Life for rule breakers is uncomfortable.

In this series we'll meet the imprisoned victims of more than 70 years of Danish colonial

mapping in America you've never heard of, and a Palestinian Shepherd who breaks all the rules.

Andreas Hartman with how I disappear.

I'm 42 years old now.
